Module: Ice Core DataLast Updated on 2011-06-07 00:00:00
SUMMARY
This is a data-driven module designed to address key questions about the stability of the Earth’s climate in the past and the factors that drive climate change. This information is essential for students who want to study current climate change using NASA data, and interprets this in a correct historical context.
This set of exercises focuses on data from ice cores and addresses questions such as:
· Is the climate stable?
· How has climate changed in the past?
· How is the level of carbon dioxide in the atmosphere related to global temperature?
· How has sea level changed in the past?
This module is based on real data,... More »

Ice Cores Yield Rich History of Climate Change
Research project completes drilling for the year,
reaching two miles below West Antarctic Ice Sheet
In late January 2011, in Antarctica, a research team investigating the last 100,000 years of Earth's climate history reached an important milestone completing the main ice core to a depth of 3,331 meters (10,928 feet) at West Antarctic Ice Sheet Divide (WAIS). The project will be completed over the next two years with some additional coring and borehole logging to obtain additional information and samples of the ice for the study of the climate record contained in the core.
As part of the project, begun six years ago, the team, has been drilling deep into the ice at the WAIS Divide site and recovering and analyzing ice cores for clues about how changes in the concentration of greenhouse gases in the atmosphere have... More »
